This picture was given to me by Nissan Teman and was taken in 1964. I am fairly sure that it was after the first Israel Day Parade down, then, Lexington Avenue - which was before they moved it to Fifth, but I could be mistaken (see comments below) as I joined Betar only in the Fall of 1964. That should be Central Park.

Please add in comments any corrections of additional info.
